For the purpose of this chapter, certain rules of construction apply to the text, as follows:
   (a)   Words used in the present tense include the future tense, and the singular includes the plural, unless the context clearly indicates the contrary.
   (b)   The term "shall" is always mandatory and not discretionary; the word "may" or "should" is permissive.
   (c)   Any word or term not interpreted or defined by this chapter shall carry the meaning of common or standard utilization.
